John Lennon's tooth used to clone dead Beatle?

One dentist hopes to make it happen by cloning the Beatle through DNA in his tooth.

Dr. Michael Zuk purchased Lennon's tooth in 2011 and since taken it around the world, used it to make a line of DNA pendants and now, handed it over to scientists to extract the DNA code from the rotted molar.

“If scientists think they can clone Mammoths, then John Lennon could be next,” Zuk said.

"I am nervous and excited at the possibility that we will be able to fully sequence John Lennon's DNA, very soon I hope," he said. "With researchers working on ways to clone mammoths, the same technology certainly could make human cloning a reality."

Zuk said the findings could be revealed in a documentary about celebrity genetics being produced in the U.K.

But even if scientists were able to use Lennon's DNA to bring him back to life, would the singer, who wrote about "living for today" even want to come back?
